OVERFLOW-ALARM FOR ICE-BOXES.

Application filed March 23, 1916.

To all whom it may concern:

Be it known that I, ALBERT om, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Overflow-Alarms for Ice- Boxes, of which the following is a specification.

This invention relates to an overflow alarm for ice boxes and has as its object to provide certain new features of construction for such a device, by means of which the same may easily be attached to and detached from a drip pan such as ordinarily used in ice boxes.

A further object is to provide, in such a device means whereby it can be regulated so as to give the alarm at any desired level of water in the drip pan.

Vith the foregoing and other objects in view, the invention consists in the particular construction, combination and arrangement of parts hereinafter more specifically described and shown in the accompanying drawing, in which- Figure 1 is a perspective view of my clevice, as applied to an empty drip pan of the usual form; F ig. 2 is a similar View, with the drip pan filled to the level at which the alarm is sounded; Fig. 3 is a perspective detail view of a part of my device, on an increased scale, detached from the drip pan.

Similar parts are designated by similar reference characters throughout the several views.

Referring more particularly to the drawing, 7 is a spring clamp having two shanks 7 and 7 and a substantially tubular portion formed on the top, where the two shanks meet, as at 8. The clamp is sprung into position on the sides of the drip pan 5, hav ing an outwardly bent and rounded rim 6. A curvature 9 is formed in the outer shank 7 of the clamp 7 adapted to admit therein the rim 6, as shown. The shanks 7 and 7 are also provided with coinciding screw holes 9 and 9 adapted to receive therein screws 9 which, when drawn tight, will secure the clamp firmly in position on the sides of the drip pan 5 and, when loosened, will permit the clamp to be removed easily. A rivet 10 is rotatably inserted in the tubular portion 8 of the clamp and provided,

at its longitudinal center, with a hole traversing it, into which is inserted a rod 11, secured in position by a set-screw 12. On the end of the rod 11 projecting into the drip-pan 5 is mounted a float 13. The lower end of the shank 7 has a boss 14: formed on it, provided with a square hole into which fits a square lug 15 carried by a mechanical bell 16. A set-screw 17 serves for removably securing the lug 15 in the said hole.

The bell 1G is provided with the well known push-rod having a bifurcated upper end 18 adapted to receive therein the outer end of the rod 11 and to be pressed down thereby when the float 13 rises to the re quired level, thus actuating the bell and sounding the alarm. By regulating the respective length of the inner and outer ends of the rod 11 the level of water in the drip pan at which the alarm is to be given may be determined.

It will be understood that while I have thus shown and described the preferred form of embodiment of my invention, I do not want to be limited to its mechanical details, but may resort to such alterations and modifications as come within the scope of the claim hereunto appended.

I claim:

The combination with a drip pan for ice boxes of the ordinary form, of a spring clamp adapted to be sprung on the sides thereof, means formed in said spring clamp for accommodating the rim with which such drip pans are usually provided, means for tightening said spring clamp on said drip pan, means for removably attaching a mechanical bell to said spring clamp, outside of the drip pan, alever pivoted in said spring clamp, having one arm projecting into thedrip pan and a float attached to it and its outer arm projecting over said bell, a push rod adapted to operate said bell and means provided on said push-rod for receiving therein said latter mentioned arm of the lever, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my signature in the presence of a witness.

ALBERT WOLF.
